So, why is this an ActiveSync bug? It's a bug in the client that  
doesn't expunge it from the folder when moving it to the trash. There  
is no method available to mark a message as deleted in ActiveSync. The  
ONLY way to remove a message from a mailbox on the AS client is to  
send it a remove command. Since this email was not actually removed  
from the mailbox, we cannot do this.
